What is BIO-DIESEL?
• Bio-diesel is diesel produced from vegetal oil
• The process is a well known technique called
«Trans-esterification». It is now profitable
because of high prices of fossil oil.
• Bio-diesel can totally replace fossil diesel, or can
be mixed with it.
• Vegetal oil from the seeds of Jatropha Curcas is
among the best source of bio-diesel.

---

Why Jatropha Curcas?
• Shrubs (2 to 5 meters) growing
on poor soils, in dry to humid
areas
• Low cost, easy to grow,
perennial plant (40 years).
• First harvest after 18 months
• Produces cheap, but toxic,
vegetal oil: no need of
subsidies to produce bio-diesel
• Farmers can make $200 to
250$/ha/year on marginal lands
• No competition with food or
cash crops

D1Oils plc
• UK company, listed on the London Stock Exchange; among the
world leaders in bio-diesel processing and production.
• Works in the UK, Southern Africa/Madagascar, India,
Asia/Pacific and Australia/New Zealand.
• Has developed a small refinery, to produce bio-diesel from
Jatropha oil that meets high quality European norms. Capacity:
8000 T/year of bio-diesel.

By-Products from Seed Cake
• Organic fertilizer with high content in Nitrogen (5%).
See results of tests on rice below.
• Jatropha briquettes could be used as substitute to
charcoal: early stage of research
•Biomass for electricity production.
